AFNetworking Request failed: unacceptable content-type: text/html

Question

I'm trying to send POST request to server, and I'm still failing to do so. Please help me out what's incorrect.

Shared instance init:

- (id)init{
self = [self initWithBaseURL:[NSURL URLWithString:kBaseURL]];
if(self) {
    self.
    self.responseSerializer = [AFJSONResponseSerializer serializer];
    [self.requestSerializer setAuthorizationHeaderFieldWithUsername:@"user" password:@"password"];
    parsingQueue = dispatch_queue_create("com.company.queue.parser",NULL);
}
return self;

post method body:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:[FSApplicationManager sharedInstance].userToken, @"user_token", nil];
[params setObject:[NSNumber numberWithDouble:userId] forKey:@"user_id"];
[params setObject:[NSNumber numberWithDouble:filmId] forKey:@"film_id"];
[params setObject:[NSNumber numberWithBool:NO] forKey:@"sendCopy"];

if([subject length]>0){
    [params setObject:subject forKey:@"subject"];
}
[params setObject:message forKey:@"message"];

NSString *URLString = [NSString stringWithFormat:@"%@%@", kBaseURL, kAPISendMessageToUser];

NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:@"POST"
                                                               URLString:URLString
                                                              parameters:params
                                                                   error:nil];

[request addValue:[self signatureWithURL:[request.URL absoluteString] requestBody:[[NSString alloc] initWithData:[request HTTPBody] encoding:NSUTF8StringEncoding]] forHTTPHeaderField:@"X-SERVAPI-Signature"];
[request addValue:pub forHTTPHeaderField:@"X-SERVAPI-PublicKey"];

AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id response){
    NSLog(@"%@", response);

} failure:^(AFHTTPRequestOperation *operation,  NSError *error){
    NSLog(@"%@, \n response %@", error, operation.responseObject);
}];

[self.operationQueue addOperation:operation];

return operation;

error I'm getting:

Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: internal server error (500)" UserInfo=0xcf0c2f0 {NSErrorFailingURLKey=https://ppd.someserver.com/api/user/send-message, NSLocalizedDescription=Request failed: internal server error (500), NSUnderlyingError=0xcf06ce0 "Request failed: unacceptable content-type: text/html", AFNetworkingOperationFailingURLResponseErrorKey= { URL: https://ppd.someserver.com/api/user/send-message } { status code: 500, headers { Connection = close; "Content-Encoding" = gzip; "Content-Length" = 1412; "Content-Type" = "text/html; charset=UTF-8"; Date = "Sun, 14 Dec 2014 13:46:57 GMT"; P3P = "CP=\"NOI ADM DEV PSAi COM NAV OUR OTRo STP IND DEM\""; Server = Apache; Vary = "Accept-Encoding"; "X-Powered-By" = "PHP/5.3.3-7+squeeze19"; } }},

I've tried to contact guy responsible for server and that is what I get:

There is no need to add the content type to your request but if you wish to do so, since your are using a POST method, you should use: Content-Type: application/x-www-form-urlencoded;

BTW, I assume this is in a AFHTTPRequestOperationManager subclass? I assume that the syntax error in init is something you tried to remove because it wasn't relevant to the question at hand? — Rob

The problem is that the server is sending you an HTML encoded answer. You can do one of these 2 options:

Talk to the server side people, to encode it as a json.
Attempt to fix it by yourself by doing the following: After setting your self.responseSerializer put this line:

self.operationManager.responseSerializer.acceptableContentTypes = [self.operationManager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

This line adds "text/html" to the acceptable types. Providing that server's response is still serializable - you should be ok.
